I think as with all who buy a scope you expect to see stars like on a xmas card,but that is not how they look,besides the moon is brilliant with a scope,there are some stars that cannot be seen with the naked eye,only time lapse phography will show them.so dont be dissapointed,is not going to get much clearer.why not join an amateur site like sky and scope or another source on the internet...best of luck and good viewing......larry@reichinstruments.com

We have a bushnell 78-8831 telescope, after assembly we still cannot view any images.


1. use the lowest power eyepiece (highest number in mm)
2. Point the scope towards a object (about 1000yds) away during the day and see if you can focus on the object. If you can not see anything during the day there is a problem either with the scope or set-up
3. Align the finder to the daylight object so it is ready for night viewing.
4. First night object should be the moon. Easy to find. ( A full moon presents poor seeing but this is just to get used to the scope.
5. Once the above steps are completed, use a good star program to find interesting objects (Stellarium, Cartes du Soliel, C2A are all freeware)
6. If you can not see the daytime object, remove the eyepiece and look down the focus tube. You should see a reflection of your eye in the primary mirror. If not, the primary and/or secondary mirror need to be collimated (aligned) refer to your owners manual.

I have a bushnell northstar 78-8831 and need to know how to reset the telescope. when in align earth mode it asks me to align star 2, skipping over star 1.


This scope has many goto issues. For one there is no way to reset the controller or to reload the firmware inside the hand controller. The firmware is probably corrupted.

You can contact their repair and support web site here:

Red dot finder scope


Simple-- you can also do this during the day on an object at least 100 yards away-- but at night; get the moon centered in the eyepiece and without moving the telescope center the red dot on the moon. This will get you almost aligned-- then put a bright star in the eyepiece and readjust the red dot to center the star.

Viewing planets and stars


The problem is you are way out of focus. Turn the focus knob alot, until the star image gets much much smaller. Keep going until it looks like a pin point or a star!. The spider vane and center black dot will disappear. This black dot is actually the secondary diagonal mirror reflection in the primary mirror. The peace signs are the secondary supports. Use the lowest power eye pieces. I would not use the Barlow lens that comes with this scope as it very poor quality. Also, using this high power with this small an aperature (tube diamter) & unstable mount will be very difficult indeed. Invest in some wide angle, long eye relief low power lens. Use these for a while before going to higher powers.

Computer not accurate


Looking through the manual (link follows) please check that you set the time in 24 hour clock with timezone correctly. Also the date & of course location. I see no reset function in the manual but I guess leaving the batteries out for a while will reset it. Manual link: http://www.bushnell.com/customer_service/manuals/telescopes/78-8876_1LIM.pdf Also although it says you do not need to know where the stars are you're aligning to it's good to have some idea that you're actually aligning with "Mizar" or whatever. You can find maps of the night sky where you are on this link: http://www.wunderground.com/sky/index.asp Finally check if there is a local astronomy group that you can join, they are always ready to encourage & help people.
